PATIENT. orrlcsf BRACKET FOR RETAINING VALVES.

Application filed September 8,1925. Serial No. 55,195.

' Retaining valves are applied to cars to replenished, if the retaining valve is in an inoperative condition, the triple valve will automatically assume a released position allowing the train to gaininoinentum, and run out of control.

in good working order at all times.

Bolts are used so as to attach retaining valves to the car under theoldpractice, the head of the bolt being on the inside. of the car. l/Vhen a retainingvalve fails, if the car is moving under load, itis necessary to.

break the seals of the car in transit to remove the load from the end of the car to get at 2 the bolts for the purpose of removing and replacing the retaining valve. vWhen the car is loaded with valuable freight, the handling and moving of the same has resulted in costly damage claims, dueto workmens carelessness, their failure to replace the freight in safe condition and location for movement on to destination.

Retaining valves have to be removed frequently and with the practice generally in e vogue the bolts holding the'valve to the car become loose,and it is impossibleto again tighten the nuts as the bolts will turn unless held by a workman on the inside of thecar,

' all of which is, jas above pointed out, very objectionable.

It is often the case that under service conditions the retaining valve pipe breaksloose at the threads where it enters thefretaining valve, this being the weakest point. Itis then necessary to replace the said pipe of' the full length from the union to the valve, which is about 20 feet long on closed cars l and about 15 feet long on open type cars.

One of the objects of my invention is to provide an anchor, or bracket permanently secured to the car t-o'which the retaining It is, therefore, ofthe ut- I most importance that the retaining valve be valve may be-secured' to and detached from without entering the car.

Another object of my invention is to provide a connection between the anchor and nfrA soN SMITH, or

retaining valve which will permit of varying lengths of pipe (within a reasonable limit) for the retaining valve without disturbing the original position of the anchor.

Other objects of my invention will readily be. suggested to those skilled in this art.

My improved retaining valve anchor, or

bracket, comprises a head 3 having. suitable bolt or rivet openings 4, through which bolts or rivets pass to secure the anchor to the car 5 permanently. A stem 6 inter-' mediate the ends of the head depends from the head and is in theplane of the head to increase the surface contact between the anchor and the car. On each side of the stem 6 is a shelf 7 integral with and depending from, and extending forwardly of the head 3 from the outer edge of which is a. depending apron 8 which is connected to the stem 6 by the spacing wall, or plate 9.

The apron 8 is provided with an elong'ated slot which, at its upper end, opens into the bolt head opening 11 through the shelf 7, as clearly shown in the drawings.

' The anchor being secured to the car, the workman, if he prefers, can slip the bolts 12 into the opening 11 and slots 10 and then position the retaining valve on said bolts by aligning the bolt openings usually provided in the lugs 14 of the anchor and then tightly the connection being a screw the nuts. 15 onthe bolts 12 thereby Y securely, and firmly locking the retaining' valve to the anchor.

In the first installation, the bolts 12 would be positioned near the tops of the slots 10, so that they could be lowered in the slots if need be to compensate for any shortening forwardljfrom the head, an apron clepend- 10 of the air pipe 1, thereby obviating the 11151 from the outer edge of said shelves, and necessity of changing the anchor from its a plate connecting the aprons with said original position. stein, a bolt opening through each of said \Vhat I claim 1s: shelves and an elongated slot in each of sald A retaining: valve bracket coniprising a aprons opening into said holt holes. 15
